6 FAQs about [Down-the-hole reverse circulation drilling rig]

How does reverse circulation drilling work?

SYSTEMS ‘Reverse Circulation’ drilling involves the supply of air down through the drill-string to decrease the ‘efective density’ of the water in the center of the drill-string. Operating much like an ‘air-lift’, the drilling spoils are carried out of the hole through this rising column lower-density air/ water mixture (see Figure below).

What is a reverse circulation drill string?

The industry’s most durable and versatile reverse circulation drill string. 2 to 3 separate drilling passages to accommodate mixtures of air, water and drilling foams. Spoils return passages up to 9.75 inches in diameter. Made in Canada, these high-quality conventional rotary bits are for rock around 100-200 MPa.

Can a reverse circulation drill be used with a rotary drill?

Reverse Circulation can be used in conjunction with rotary drilling bits as well as Down-the-Hole-Hammer applications. The Berminghammer Reverse Circulation Drills are particularly well suited to Down-the-Hole-Hammer applications due to their simple, rug-ged design and construction. Drill Depths up to 200’

What is a Berminghammer reverse circulation drill?

The Berminghammer Reverse Circulation Drills are particularly well suited to Down-the-Hole-Hammer applications due to their simple, rug-ged design and construction. Drill Depths up to 200’ Used with both the BRC Drills and RC Swivel, Berminghammer’s drill string is the most durable and multi-versatile drill string in the industry.

What is a swivel drill rig used for?

Typical applications are hard rock and case advance drilling. High quality swivels designed to adapt traditional European drill rigs for reverse circulation rock drilling. From 24” (with down-the-hole-hammers) through 120" diameter cluster drills and everything in between.

What is a productive drill rig?

Productive drilling occurs when the majority of the time spent on-site is devoted to actually drilling. Many competitor drill rigs involve time draining activities such as: long rig-up times, difficult and time consuming pile placement, adding more and splicing piles.
